Who I Am
I'm a Senior Full Stack Developer with 6+ years of experience building scalable web applications and collaborating with technical teams. I specialize in MERN stack development and AWS Amplify, delivering robust solutions that optimize performance and maintain hands-on coding contributions.
Throughout my career, I've engineered scalable medical applications serving 20+ clinics, developed winery management platforms, architected investing platforms, and built research collaboration tools. My work focuses on creating applications that not only meet business requirements but also exceed performance expectations.
I'm passionate about mentoring junior developers, achieving high test coverage, and implementing best practices. I'm also expanding my backend toolkit. I've completed Python fundamentals and successfully migrated an application from Node.js to FastAPI, demonstrating my ability to adapt and deliver across different technology stacks.
My Mission
To deliver high-quality, scalable solutions that exceed client expectations. I'm committed to optimizing performance, achieving high test coverage, and mentoring the next generation of developers. My goal is to build applications that make a real impact while maintaining code quality and best practices.
